I have to wonder about box frames. For 1 thing, C channel is used in heavy trucks. If the C can't be stiff enough, and fit in required space, double the C.
Plus, if need to add a bracket to mount something, drill thru the vertical part, use bolt to fill hole, and torque tight with nut and flat washer. Loose very little strength unless big hole.
